Therefore, the dust cleaned from the dustproof film 4 can be synchronously discharged outside through the water outlet in the water tank 3, so that the water in the water tank 3 is kept in a clean state.
The water supply mechanism comprises a water accumulating tank 13, the water accumulating tank 13 is fixedly arranged on the cleaning tank 2, a filter layer 12 is further arranged in the water accumulating tank 13, the top of the water accumulating tank 13 is a filter plate 14, the water accumulating tank 13 is divided into a water accumulating chamber and a water containing chamber through the filter layer 12, a water guide pipe 11 is further arranged below the water containing chamber, one end of the water guide pipe 11 is communicated with the water containing chamber, and the other end of the water guide pipe 11 is positioned in the water tank 3. Rainwater is collected to ponding case 13 in this scheme in rainy day, and filter plate 14 at ponding case 13 top plays a filterable effect to impurity such as some leaves, and it is indoor that the rainwater enters into the ponding in ponding case 13, can be so that the further obtaining of rainwater filters through filter layer 12. The filtered rainwater enters the water containing chamber and is discharged into the water tank 3 through the water guide pipe 11. Thus, each time rain falls, water in the water accumulating tank 13 enters the water tank 3, so that the water in the water tank 3 is replaced, impurities such as dust and the like in the water tank 3 are removed, and the water in the water tank 3 is kept in a clean state. The filter layer 12 is an activated carbon filter layer. The filtering layer 12 of the activated carbon can realize efficient purification treatment of rainwater, and meanwhile, the price of the activated carbon is not high, so that cost overhead can be controlled.
The method comprises the following specific operations: in windy weather, the fan blade 15 outside the cleaning box 2 is blown by wind and rotates, the corresponding drive roll 6 that makes of rotation of fan blade 15 rotates, and through setting up the runner on drive roll 6, first roller 5 and second roller 7 respectively to and the conveyer belt 8 that cooperatees and use on the runner can make the corresponding rotation of first roller 5 and second roller 7, the rotation of first roller 5 and second roller 7, makes the corresponding rotation of dust-proof membrane 4. This allows the dust-proof film 4 with dust on the monitor probe 1 to be transferred into the clean box 2, and the clean dust-proof film 4 is replaced on the monitor probe 1. This operation achieves cleaning of dust on the surface of the monitor probe 1. The dust-proof film 4 with dust enters the clean tank 2 and also enters the water tank 3. The rotation of the second roller 7 in the cleaning tank 2 causes the connecting rod 9 to rotate, and the corresponding rotation of the cleaning roller 10 at the other end of the connecting rod 9 facilitates further cleaning of the dust on the surface of the dust-proof film 4. The dust-proof film 4 after cleaning passes between the first roller 5 and the drying roller 16, and the drying roller 16 further cleans the dust-proof film 4, so that a clean dust-proof film 4 can be obtained for the next time of replacing the dust-proof film 4 on the surface of the monitoring probe 1.
The water supply mechanism in this scheme for collect the rainwater to carry out cleaning to the rainwater, reach the effective utilization to the rainwater, make every time rain alright change the processing with the water in 3 water tanks to in the clean box 2, clear away the dust that leaves because clean dust-proof membrane 4 in 3 water tanks. The rainwater is collected and utilized, no cost is generated, a better using effect can be obtained, and the practicability is high.
